Poetry on Delhi Smog

In light of the air pollution episode in Delhi, the following poem has been circulating on social media:

No one noticed
When the sparrows left
It was just another
smoggy winter morning
People drove their cars
dropped their children off
At air conditioned schools
Where they learned
Pollution is a bad thing
It was just another
smoggy winter morning
And stuck on flyovers
No one noticed
That they spent more time on roads
Than with family and friends
So the city of traders
Traded its sparrows,
for SUVs
And children’s lungs
for Diwali firecrackers
Pollution was good for business
And as a million bonfires
lit up in Punjab and Haryana
Delhi bought air purifiers,
masks, cough syrup
and tweeted in angerBut it all started On a smoggy winter morningWhen the last sparrow left No one noticed,As that ever useful smogHid us from our conscience
